RegisterClass and CreateWindow
BOOL InitApplication(HINSTANCE hinstance)
{
WNDCLASSEX wcx;
wcx.lpszClassName = "MainWClass"; // name of window class
}
hwnd = CreateWindow(
"MainWClass", // name of window class
这两个值是有关联的，需要保持一致，否则窗口不能注册，也显示不了。
该参数的解释：
A null-terminated string or a class atom created by a previous call to the RegisterClass or RegisterClassEx function. The atom must be in the low-order word of lpClassName; the high-order word must be zero. If lpClassName is a string, it specifies the window class name. The class name can be any name registered with RegisterClass or RegisterClassEx, provided that the module that registers the class is also the module that creates the window. The class name can also be any of the predefined system class names. For a list of system class names, see the Remarks section.
scanf使用中断
scanf("%s", str, length); length 这个长度一定要配置
scanf("%legth s",str); 这个不会报错，但是会中断
具体原因得看源代码的实现方式
